Batteries - A fully charged 9V 400mAh managed to drive the esp32-cam 
  • AP mode for 1hr 35 min
  • STA mode for 2hr 5 min

So it seems that AP just need a bit more power than the STA mode. The AP mode is especially interesting when we want to have a mobile webcam server mounted on a robot car or perhaps a flying drone. Using an Android or iPhone one can connect to the AP and stream the picture frames to her phone.

We can also install "out in the field" webcam server using AP mode of esp32-cam, for example, greenhouses and farms.

Esp32-cam can operate in both AP and STA mode. This provides us with the opportunity to build a socket-based network of esp32.




 I have uploaded simple experimental webcam servers to the GitHub.

Custom made - Sometimes, it is nice to be able to build custom made things. Thanks to Damien George and all the clever people at micropython.org for making it easy. So that, to custom build a micropython is not that difficult. Why do you want to build customize firmware anyway? Well, you might want to include some functionalities of your own and removed some functionalities from the standard distribution. The choices are there for you to make. I have a few changes that I want to make in micropython. version header -kaki5 (pronounce kaki-lima) an additional thread cleanup function for esp32 add frozen modules CryptoXo and uasyncio remove help, upip, and webrepl camera C module for esp32 camera board These are accomplished by modifying and adding files. py/makeversionhdr.py py/modthread.c extra/CryptoXo.py, extra/uasyncio.py, and manifest.py mpconfigport.h main.c and modcamera.c I also want to remove some modules specifically, help, upip, and webrepl from esp32...

Multi-threading : I previously used an uasyncio webcam server. This time around, I am testing a multi-thread webcam server. The result is promising. A multi-thread server seems to give a better throughput. The program logic is simpler when compared to the server based on uasyncio. The server is a four threaded application, two for port 80, one for port 81, and port 82 runs on the main thread, which blocks the REPL.  You can start a dedicated thread for port 82 if you do not want to block the REPL. I found pix/7 gives the best performance. A spe/2 will reduce the image size but give you a grayscale image. Please see my previous blog if all these seem mysterious to you. I have compiled a new firmware, MicroPython v1.11-571-g7e374d231.  You can download the new firmware from my repository at GitHub. The soft reset is not functioning properly. You need to do a hard reset. I also include four new functions in modcamera.c: pixformat agcgain aelevels aecvalue The pixfo...

Micropython - v1.11-498 introduced a few changes in the source-code directory structure. Changes to specific files, as previously described in esp32-cam , will no longer work. A simple working summary on how to build esp32-cam firmware is described below: Make a recursive copy of ports/esp32 to ports/esp32-cam, and you will need to modify the following files: 1) ports/esp32-cam/main.c 2) ports/esp32-cam/Makefile 3) ports/esp32-cam/modcamera.c 4) ports/esp32-cam/mpconfigport.h 5) ports/esp32-cam/boards/manifest.py 6) ports/esp32-cam/boards/sdkconfig.base Or, you can just download a precompiled Micropython v1.11-498 from firmware.bin at GitHub if you want to save some work. However, I encourage you to compile the firmware yourself. You will learn a lot and you can choose to modify anything to your liking. The modcamera.c includes something new. The still photo was taken using these settings; pix =8, con =2, qua =10, and spe =2. You will understand those parameters, later...
